Spark Plug Thread Repair kit for 14mm Threads in Alu Heads

If you have a cross threaded 14mm x 1.25mm spark plug in an Aluminium head, then this is the perfect little kit to rectify it.
The tap gradually cuts the 14mm thread, slightly wider so that the thread is cleaned up, and you can fit the machined aluminium insert into the spark plug hole.
The inserts provided in the kit have a stop at the top so once you have selected the length of insert you need it will stop when fully inserted.

Please Note:
